Duracell CR2025 3V Lithium Coin Battery 4 Pack - Long-Lasting Power

In this review of the Duracell CR2025 3V lithium coin battery, the bottom line is simple: it is a reliable spare power source for small electronics and security devices that also prioritizes safety for households with children. The reviewer finds the four-count pack best suited to people who need long shelf life and dependable performance in key fobs, car remotes and medical monitors. The single biggest reason to buy is the combination of a guaranteed 10-year storage life and child safety features that reduce accidental ingestion risks.

Key Features

• Long shelf life: A guaranteed 10-year storage life means these cells are ready when a device needs them without frequent replacement.
• Child safety features: A non-toxic bitter coating on the cell and child-secure packaging are designed to discourage swallowing and limit access by children.
• Wide compatibility: Sized as CR2025, these 3V coin cells fit common devices such as key fobs, car remotes and glucose monitors.
• Reliable performance: Customers report consistent, long-lasting power in everyday devices, offering dependable operation for sensors and remotes.
• Pack size convenience: The 4 count pack provides spare batteries for multiple devices or future use without taking up much space.

Who It's For

These CR2025 batteries are ideal for homeowners, drivers and anyone who keeps small electronics on hand for daily use. They suit people who value a long shelf life for emergency kits, medical devices like glucose monitors, and vehicle or garage remotes. The added safety measures make them a reasonable choice for families with young children who are concerned about coin cell ingestion.

Consumers who regularly swap batteries in high-drain devices or need rechargeable options should look elsewhere, as these are primary lithium coin cells meant for low-drain electronics. Also, if you prefer packaging that is easy to open without tools, be prepared for child-secure packaging that can be difficult to access.
